Description

Billions of people use the services of critical infrastructure providers, such as ambulances, hospitals, and electricity and transport networks. This number is increasing rapidly, yet there appears to be little protection for many of these services.

IT solutions have allowed organisations to increase their efficiency in order to be competitive. However, do we even know or realise what happens when IT solutions are not working – when they simply don’t function at all or not in the way we expect? This book aims to teach the IT framework from within, allowing you to reduce dependence on IT systems and put in place the necessary processes and procedures to help protect your CII.

Lessons Learned: Critical Information Infrastructure Protection is aimed at people who organise the protection of critical infrastructure, such as chief executive officers, business managers, risk managers, IT managers, information security managers, business continuity managers and civil servants. Most of the principles and recommendations described are also valid in organisations that are not critical infrastructure service providers. The book covers the following:

Lesson 1: Define critical infrastructure services.

Lesson 2: Describe the critical infrastructure service and determine its service level.

Lesson 16: Assess the security level of your information systems yourself and ask external experts to assess them as well.

Lesson 17: Scan networks yourself and ask external experts to scan them as well to find the systems that shouldn’t be connected to the Internet but still are.

Lesson 18: Prepare business continuity and disaster recovery plans and test them at reasonable intervals.

Lesson 19: Establish reliable relations and maintain them.

Lesson 20: Share information and be a part of networks where information is shared.

Lesson 21: Train people to make sure they are aware of cyber threats and know the correct behaviour.

Lesson 22: If the CII protection system does not work as planned or give the desired output, make improvements.

Lesson 23: Be prepared to provide critical infrastructure services without IT systems. If possible, reduce dependence on IT systems. If possible, during a crisis, provide critical services at reduced functionality and/or in reduced volumes.
